BYPASS rocker switch enables the rear panel BYPASS inputs. The
overall gain of the preamplifier remains fixed at 0 dB (unity) gain. All
other preamplifier functions are disabled except for record functions. All
previously selected front panel lamps are not illuminated with the
exception of the BYPASS and selected RECORD input lamp. Pressing the
lower section of the BYPASS rocker switch or selecting any other Listen
input will restore normal operation. The previously selected LISTEN
Input lamp is illuminated and the BYPASS lamp is not illuminated.

image is shifted to the left or right slightly for each press of the BAL L or
BAL R button. Each press equals a total channel imbalance of 1 dB. For
each 0.5 dB that one channel is offset, the opposite channel is offset in
the opposite direction by 0.5 dB. This feature maintains that the absolute
volume level will remain the same even though the image will be shifted
by a specific amount. A total of six (6) presses on each button (3dB) can
be achieved which will give a total imbalance of 6 dB between right and
left channels. Either the L or R lamp will be illuminated to indicate a
channel imbalance. Otherwise, neither L nor R lamp is illuminated.

M
volume, while rotating the knob counterclockwise decreases volume.
The VOLUME control provides a fixed range of 63.5 dB in increments of
0.5 dB throughout a rotation of 230 degrees. The 63.5 dB range remains
constant, independent of the overall gain selected by the GAIN rocker
switch mentioned above. The VOLUME control does not utilize mechani-
cal end-stops to indicate minimum or maximum volume settings. The
numerical position of the VOLUME control is indicated when the remote
sensor/display unit is utilized.
